Detailed Description

Sunsong 3403985 is a power steering return line hose assembly made for the 2001-2006 Hyundai Santa Fe, specifically the return line to cooler routing. It is built to meet original equipment performance expectations in the return circuit, where fluid pressure is lower but heat exposure and contamination resistance still matter. The steel tubing and zinc-plated finish help protect the line in harsh underbody conditions, while the application-specific design supports a proper OE-style replacement. This part cross-references Dorman - HELP 80995 for the same application.

Common Problems This Part Can Help Solve

• Power steering fluid seepage from a worn return hose
• Corrosion damage on the original steel line
• Cracked or hardened hose sections from heat exposure
• Restricted return flow caused by a deteriorated line assembly
• Noise or steering performance issues related to fluid loss

Installation Notes and Tips

Verify routing before removal so the replacement follows the original path to the cooler on the Hyundai Santa Fe. Inspect mating connections, brackets, and nearby heat sources during installation, and replace any worn retainers or protective components that are part of the vehicle’s original setup. After installation, refill the system with the correct power steering fluid and check for leaks with the engine running and steering cycled lock-to-lock.
